JOHN \V. GIBBONEY, OF LYNN, MASSACHUSETTS.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 426,005, dated April22, 1890.

I Application filed November 5, 1887. Serial No. 254,439. (No model.)

To to whom it may concern.

Be it known that I, JOHN W'. GIBBONEY, a citizen of the United States,residing in Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in IyperitingMachines; and I do hereby declare that the following is a full, clear,and exact descrip tion of the invention, which will enable othersskilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to type-writing machines, and particularly to thatclass of typewriters in which the paperis carried and supported upon amovable carriage, moved forward as a characteris printed bythepressureof a finger.

My invention relates to an improvement in the feeding mechanism oftype-writers; and it consists of peculiar and novel arrangements anddevices whereby the shifting of the position of the traveling carriageand the times of the feeding of the paper are more perfectly under thecontrol. of the operator.

The object of my invention is to lessen the number of motions requiredin operating, the machine, and as these motions consist of many thousandin the course of a days work, any device which shall materially lessenthe number of these operations or mot-ions must necessarily be valuableand important.

My invention provides a simple and effective means whereby the operatormay, with a single hand and at pleasure, move the carriage backward andforward freely at will without producing a feed of the paper from lineto line.

My invention avoids the objectionable fea tures incident to theapparatus before mentioned, and consists in the combination, with theline-t0-line feed-pawl in a t-ypem'riting machine, of a carriagereleasing mechanism operated by a releasing button or key and mounted inposition to be engaged by the hands of the operator when grasping thefeed-lover.

In the accompanying drawings, Figure 1 is a side elevation of myinvention as applied to a Remington type-writer. Fig. 2 shows amodification in the manner of supporting the releasing button or key.

In Fig. 1, A is the ordinary carriage, upon which is mounted thepaper-feed roll B. C is the ordinary hand-lever mounted on saidcarriage, and having a depending handle at the front of the machine nearthe letter-keys in position where it may be readily grasped by theoperator when he wishes to move the carriage back to begin a newline.This lever operates upon suitable releasing mechanism for throwing thespace-feed devices at the rear of the carriage out of action, so as torelease the carriage in the well-known manner and to permit it to movefreely without opposition from such spacing devices. The mechanismwhereby such feed-lever effects this result I term thecarriage-releasing mechanism. This mechanism differs in different typesof machines; but my invention is ap-' plicable to any machine in whichthere is a feed-lever adapted to be grasped by the hand of the operator,as in the Remington machine, and mounted 011 the carriage for thepurpose of permitting the operator to throw out of action the space-feeddevices and move the carriage backward or forward.

D is the ordinary feedpawl mounted on the hand-lever, and adapted tomove the paper roll B one tooth when the outer end of the hand-lever israised coincidently with the act of grasping the same for the purpose ofmov ing the carriage backward to begin a new line.

G is the vibrating rack, pivoted at g, and II II are the rack-pawls usedin spacing.

The auxiliary button or key of my invention is indicated at T as athumb-piece in position to be acted upon by the hand which grasps thelever C. The button T is upon a lever E, which is mounted to move withthe carriage and lever, being for this purpose suitably pivoted on acollar secured to lever C, as shown.

In the form of my invention shown in Fig.

1 the auxiliary button or key T is made to operate to release or throwout the line-to-line feed, which is accomplished through any suitableintermediate mechanism connecting the button and the pawl D-as, forinstance, a rod or link F, connected with the tail of the pawl D. 'Bypressing upon said releasing key or button at the same time that thehandle 0 is raised, so as to throw the vibrating rack G out ofengagement with the pawls, the carriage may obviously be quickly movedbackward or forward to any desired point Without moving the paper fromone line to the neXt.

Ordinarily an upward motion of the feedlever C by the hand presses downthe rear side of the vibrating rack G and throws it out of engagementwith the pawls H H; but this movement also, acting through the feedpawlD and ratchetwvheel B, rotates the feedroll and carries the paperforward from one line to the next. This latter movement is not alwaysdesirable, as in tabular and other similar Work, but may be omitted atpleasure by operating the auxiliary key by the thumb at the same timethat the feed-lever is grasped and lifted in the act of moving thecarriage.

The auxiliary key or button, instead of being on a lever pivoted to thelever 0, might be on one pivoted directly to the carriage A, as shown inFig. 2. As before, however, the thumb or finger piece is located inposition near lever C, and both lever C and the auxiliary button or keymove together with the carriage.

l/Vhen with either of the above arrangements the carriage is to beshifted back to begin a new line, the lever O is operated in the usualway without operating the auxiliaryfbutton or key T, with the usualeffect of producing a feed of the paper from one line to the next.

WVhat I claim as my invention is 1. In a type-writer, the combination,with a line-to-line feed-pawl, of a key connected to said pawl andmounted in position to be engaged by the hand of 'the' operator whengrasping the feed-lever and carriage-releasing mechanism operated bysaid feed-lever.

2. The combination, with the hand-lever G, mounted on the carriage, ofthe feed-pawl D, paper roll B, the button or thumb-piece T, mounted onlever O, and a link F, connecting the pawlD with the lever carrying thethumbpiece.
